What's the purpose of the small pair of holes between each combustion chamber on an 885 head, which aren't present on a 731 head? These mate with the same holes in the block...
Just had a bit of a eureka moment, realising the in-flow from the block is actually through the single, larger central bolt hole (right?)
Looking to buy a 731 and was concerned about block compatibility. Everything I've read suggests they're bolt-on compatible...
